Howdy-

Tree fell on boat.

I've got two punctures and a 7 inch gash in the bottom of my GREGOR Aluminum boat.
Anyways- The punctures are about 1 inch long by 1/8th inch wide and on the floor right inside the little water collection lines way towards the bow under the forward seat. The holes look like a quarter was forced through on it's edge.

Ideas that have been going around-

*Of course, have a Pro do the repair.
*ADHESIVE weld the punctures (what works better than JB?)
*Smash a piece of hot aluminum nugget into punctures and beat with a hammer until it fills the void, then paint over it with JB. (would lead nugget work?)

Just trying to get this boat back on the water for some salmon action while it's hot. Money got tight after a car expense.


What have others done, and how long did it last?



There's a couple other things needing attention on the boat, so it is a little bit of a project.

There is a couple of things that will need real welding, but I am trying to save $$ on the rest. There are some things that a PRO welder can do best, and I might drop coin for that, but I like to do as much as I can myself.


I think I can fix the front seat and replace 4 feet of gunnel. There is also a gash (7 inches) that I plan on sandwiching between two pieces of aluminum sheet, filling with glue and then riveting around it. It is just above the waterline.

I need to decide on adhesive or welding for the two punctures.

I'm wondering what others have found with the following adhesives on aluminum boat repairs-

PC11
MARINE TEX
4200
5200

I've heard from several people that the PC11 will do the holes good, and is even removeable with heat later on for "real repair" if neccesary. The others were suggested to be used in place of JB weld for other repairs.

I'm probably going to make a wood bench seat to replace the aluminum one in the front of the boat, saving myself from the 8 welds that need to be prepped to hold the seat in position. I will rivet some aluminum L stock onto the sidewalls to support the seat and act as a forward bulkhead and I am looking for an adhesive that would work good along with some rivets. This is how my 12 foot aluminum works. Should be fine.


Speaking of rivets- what rivets should I be looking for? I know very little in the world of aluminum riveting.



Thanks!

Photos below are from second day of work. I will post pics from today soon.

How the Front seat is fixed on my 12 footer. I'm planning on doing similar with the repair on this 14 footer to save energy and $$. Welding old broken seat back in place is 8 weld tabs....

This way I use some rivets, adhesive and some bent sheet aluminum.12 seat.jpg

Use 1/4" diameter closed end blind rivets dipped in epoxy for a sturdy and waterproof installation.

I use Loc-tite marine epoxy adhesive for aluminum.

FWIW, boat repair on a shoestring doesn't usually last or achieve the desired results.

You might want to wear 2 PFDs if you're going to take that boat out on anything other than a farm pond.
